and you are doing that on the extracted value, most of these in ground values running around, like the 37B for ramaco that was on unilad, are off of head grade let alone what can actually be extracted.

im thinking the 800 x 200 drill grid top to bottom with 60m depth should net a crazy big MRE to inferred (comes down to how ballsy the resource modeller is) but within that is a good size to 20-40m deep indicated resource to do a study off. Need a stupid big MRE to catch the eye of non-technical types, like politicians. ARR is a perfect example of this, they lean into their 2.7 Bt resource heavily despite it being a 540 year mine life at 5 mtpa and irrelevant for economics..
